I've got a bundle of coaxial cables running from the cable connection on the ground floor to the attic above the first floor - a distance of roughly 20 feet. Initially, I planned on using one of the lines to fish through a few strands of paracord and be done with it. However, I've now realized that spray foam was applied at each pass the bundle makes through a fire break (this should have been obvious to me). I'm wondering what my options are for getting new cable up along the path the original bundle takes. Additionally, there's no guarantee that it's a straight path.
Are there any clever options that don't require breaking down drywall?
